Abstract (en)
[origin: MX2020008051A] Device for producing a tnt material from crimped endless filaments, with at least one spinning device for spinning the filaments and a deposit conveyor for depositing the fibers in a deposit region. in the direction of transport of the tnt blanket behind the deposit region, at least one first pre-compacting device is arranged. a suction device is provided, with which process air can be sucked through the deposit conveyor in the fiber suction region and / or in the region of the first precompaction device. Downstream of the first pre-compaction device in the direction of transport, a second pre-compaction device is connected, and in the region of the second pre-compaction device, process air can be sucked through the tank conveyor. in the region between the first pre-compacting device and the second pre-compacting device, an aspiration gap section is arranged, and in the aspiration gap section, there is no process air aspiration and / or being that the suction breach section is installed on the condition that there is less suction of process air there than in the region where the fibers are deposited and / or in the region of the first pre-compaction device and that there is less suction process air than in the region of the second pre-compaction device.
